WILL MARK BRAINLIST TO WHOEVER ANSWERS FIRST1 Sally wants to save for a new cell phone. She opens a bank account with $40 and adds $20 each week. Which of the following equations can be used to determine how much she has after ‘w’ weeks?
A . T = 60w
B . T = 40 + 20 + w
C . T = 20 + 40w
D . T = 40 + 20w

D is my answer

B is my 2nd choice but im going with D hopefully im right and if I am, lmk

Step-by-step explanation:

remember it says which of the following equations can be used to determine NOT how much she will have after "w" weeks so it is not A.

C. is wrong because the 40 is supposed to come before the 20.

T = 40 + 20w
